The site has been continuously occupied since Neolithic times. First mentioned in the 19th century BC in Egyptian inscriptions, its name was Hellenised to Pella, perhaps to honour Alexander the Great's birthplace. The Roman city, of which some spectacular ruins remain, supplanted the Hellenistic city. During this period Pella was one of the cities making up the Decapolis. The city was the site of one of Christianity's earliest churches. According to Eusebius of Caesarea it was a refuge for Jerusalem Christians in the 1st century AD who were fleeing the Jewish–Roman wars
